If f(x)= { abs(x-3)/(x-3) if x does not =3 then f(x) is:

1 if x=3

a) Undefined at x=3

B) continuous from left at x=3

c) Continuous at x=3 ( from both sides)

d) continuous fro right at x=3

e) differentiable at x=3

The answer would be a) correct? since it is disscontinuous at 3 for abs(x-3)/(x-3)?
